Patented May 24., 191a.

Application filed July 6,1909. Serial No. 505,952.

T 0 all whom it may concern: 7

Be it known that I, FRANCIS H. RICHARDS,

a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Coiling Mechanism, of which the following is a specification.

This invention relates to coiling mechanism and has for an object to provide coiling mechanism embodying improved stock forming and feed rolls capable of forming the stock and delivering the formed stock directly from the working pass between a pair of forming rolls into coiling mechanism and effecting the coiling by virtue of the forwarding movement of the bite of the forming rolls.

In my application Serial No. 105,273, for rolling mechanism filed April 30, 1902, I have disclosed and claimed mechanism comprising a pair of rolls one located interiorly of the other and provided with cooperative die faces for re-forming br changing the cross sectional configuration of a stock bar.

In my application Serial No. 502,205, for coiling and feed mechanism, filed the 15th day of June, 1909, I have disclosed and claimed a feed mechanism comprising an internal face roll in combination with an external face roll for feeding directly to a coiling device.

The present invention relates to mechanism for making eflicient a combination of these two inventions, namely the stock form-Q ing rotary dies for feeding directly to a; die the stock which is fed forward coilin and ormed at the working pass between A pair of feed rolls which will engage the stock and drive this forward into,a coiling die must ordinarily have the stock iengaging faces so formed as to produce an inappreciable amount of distortion or disfiguration of the stock which is being fed forward. In'the present invention, however, the feedin rolls are also forming dies and give a formation to the stock Whichis being fed forward by them and this fact is taken advantage of and the rolls will have a greater driving or forward ing action upon the stock than will rolls,

which are designed with a view to preventing the disfiguration of the stock. The forwarding action from the working pass of a pair of forming rolls before being engaged by any other surface than that of the forming rolls is to immediately pass it into the coiling die and the forwarding movement from the working pass is employed for driving the stock through the forming die.

This invention is particularly useful in placing an armor upon an insulated wire, and when such armor is iven a proper configuration by the forming rolls it will be flexible.

In the drawings accompanying and form ing a part of thlss ecification a practicable embodiment of a orm of my invention is illustrated wherein Figure 1 is a top plan View partly in horizontal section. Fig. 2 is a section taken on about the plane indicated by the line 22 in Fig. 1, looking toward the left, the internal rolls, however, being omitted in this view. Fi 3 is a section taken on about the plane indicated by the line 3-3 in Fig. 1 looking toward the right. Fig. 4 is a side elevation partly shown in vertical central section. Fig. 5 is an end view of the machine looking at this from the left hand end of Fig. 1. Fig. 6 is a view similar to Fig. 5 showing the end plate and the stock guiding mechanism removed. Fig. 7 is a section taken on about the plane indicated by the line 77 in Fig. 1 looking toward the right. Fig. 8 is a view taken on a plane at about the line 88 in Fig. 1 also looking toward the right. Fig.9 is a view similar to Fig. 8 but omitting the bearing or carrying member for the inner rolls. Fig. 10 is a top view of the inner rolls, their carrier mechanism and driving pinions. Fig. 11 is a side view; and Fig. 12 an end view of the parts shown in Fig. 10. Fig. 13 is a portion of the product of the machine partly shown in elevation and partly shown in longitudinal section; and Fig. 14 is a longitudinal sectional view of the coilin die.

The power for driving 1; e mechanism of respective ends 19 and 20 of the machine frame, which ends with the base of the frame constitute a gear box. The shaft 16 has fast upon it pinions 21 and 22. The pinions 21 and 22 are respectively for driving the inner and the outer forming and feed rolls. The pinion 22 is in mesh with a gear wheel 23 which is fast upon a shaft 24, such shaft being supported in bearings 25 and 26 carried by the end members 19 and 20 respectively. The shaft'24 carries a pinion 27, in the present instance located at some distance from the bearing 26. Between the pinion 27 and the bearing 26 the shaft 24 is surrounded by a bushing 28 of some anti-friction material, which bushing is supported by a bearing portion 29 of the bed of the machine frame. The pinion 27 is for driving the outer roll and is in mesh with gear teeth 30'upon the outer perimeter of a ring 31. The ring 31 is rabbeted and carries the outer roll 32 which constitutes the outer member of the rolls and has upon it a circular internal die face 33. The roll 32 and ring 31 will be fastened together by some suitable means, as for instance by pins 34. The ring 33 is provided upon its outer periphery with a bearing face which is partly supported by the machine frame and partly by two pairs of anti friction rollers, which rollers in function will presently be described. i

There is loosely mounted upon the shaft 24 a pairof gear wheels 35 and 36 which gear wheels are fast together. The gear wheel 35 is in mesh with the pinion 21 and the gear wheel 36 is for the urpose of driving the inner forming and f ded rolls 37 and 38. The rolls 37 and 38 have faces 39 and 40 upon their perimeters which are complemental to and coiiperative with the die face 33 for engaging, forming, and feeding forward the stock, as for instance a strip 41,- of

material which is to be coiled around insu-' lated wire 42. The inner rolls 37 and 38 are mounted u on shafts 43 and 44 res ectively which sha s are provided with bearings in a'carrier member 45. The carrier member is held in position at its end farthest from the rolls by means of a clamping member 46, and suitable set screws. The rolls are at one side of the clamping member 46 and the shafts 43 and 44, where these project from the other side of the clamping member, are provided with pinions 47 and 48 respectively which mesh with the gear wheel 36. In the present illustration the distance between centers of the pinions 47 and 48 is such that they cannot be placed in the same plane, consequently they are arranged in parallel planes and slightly overlapping, the. gear wheel 36 being made broad enough to accommodate these pinions when so constructed and 10-- cated. Suitable set nuts49 are shown for holding the rollers 37 and 38 in position upon the shafts.

The gearing herein illustrated is of. such relative proportions that the surface speed of the die 33 and the die faces 39 and 40 will be the same and move in the same direction, and each of these ,faces will be positively driven by a direct connection to the main source of power. i S Means are shown for effecting the desired amount of pressure with which the inner rolls will be forced against the stock and against the outer roll. A pin 50 is shown as carried or mounted in the portion 29 of the frame. The pin 50 is shown as screw threaded at its carrier end and as abut-tingLthe bushing 28 for holdin this in position. This is merely a means ot making the pin do a double duty, for its main object is to carry a pair of set nuts 51 at its free end for bearing upon the end of the carrier 45 farthest from its clamp 46 and pressing the die faces 39 and 40 of the rolls 37 and 38 against the die face 33 of the outer roll 32. The pin 50 passes through an opening 52 in the carrier member 45 and this opening is made sufli ciently large and of such an internal configuration as to permit of the required movewill be desirable to prevent or limit the inward movement of the die faces of the inner members toward the die face of the outer member, and for this purpose an adjustable abutment or stop 53 will be provided, which is in the form of a screw passing through the carrier 45 and endand'that the pinions are at the end which is secured to the machine frame, therolls being at the farther or free end. There will be sufficient yieldability in the carriage 45c and the pin 50 to permit the rolls 37 and 39 which are at the extreme end of the carriage from the fastening device 46 to be properly adjusted and to accommodate themselves to irregularities in their work.

Reference was heretofore made to antifriction rollers for engaging the outer perimeter or bearing face of the roll 32. The roll 32 is sup orted on each side of the ra-- dial line passlng through the center of the arc of' contact of the Jnner and the outer rovided with a set nut 54. The carriage 45 is constructed and adapted.

ments of adjustment. In some instancesfit rolls by a pair of antifriction rollers. The

rollers 55 and 56 arein position to receive the working thrust of the roll 37 against the roll 32. These antifriction rollers areset rather closely together and the line drawn from the center of the roll 32 will pass through the center of the roll 37 and between the anti-friction rollers 55 and 56. This line for convenience is illustrated and is given the reference character 57. These anti-friction rollers being located as they are will receive the working thrust and being located not in the line of the thrust but on each side of the same will have distributed between them and between their journals 58 and 59 the strain and the friction. Another pair of rolls 60 and (31 will be similarly positioned in respect of the roll 38 for the purpose of supporting the roll 32 against the working thrust of the roll 38. The outer surfaces of one or more of the inner rolls will, when the nature of the material requires and will permit, be suitably formed or roughened for increasing the bite and the friction between the material and such roll or rolls. The roll faces or die faces 33, 39 and 40 are at a considerable distance from the driving gears to afford ample space between these two parts of the mechanism in which to lead off and dispose of the product of the machine.

The stock, in the form of a steel ribbon, when the machine is used for armoring insulated wire, will be supplied to the ma chine from some suitable source and will be passed over a guide 62 which guide has a flat face 63 for receiving the flat face of the stock and side guides 64 for engaging the edges of the stock. The development of the guide face 63 is cylindrical and the guide faces 6464 and G3 are disposed in a spiral of about ne-half a convolution, and of steep pitch. These guide faces may be cut on a screw cutting lathe. The guide face 62 will change the direction of the path of movement of the stock without exerting any edgewise distortion or strain upon it and will convey the stock to the working pass in a straight path and in a line normal to the line of movement of the roll surfaces, so that the stock will be fed through the end plate 65 of the machine, past the ring 31 and the securing portion of the roll 32 and be resented to the working pass between the ace 39 of the roll 37 and the face 33 of the roll 32 in a direction coinciding with the path of movement of such faces at such working pass. The material will be engaged at such working pass and will be crimped 0r pressed into the desired formation and will be assed on to the working pass between the ace 4.0 of the roll 38 and the face 33 of the roll 32 where the forming of the stock will be finished or completed. By referring to Fig. 13 a form which the stock will be given when it is desired to make an overlapping flexible armor is illustrated.

The guide member 62 is shown as pro Vided with a hub 66 which is mounted upon astub shaft 67 carried by a lever 68. The guide member 62 after having been adjusted to its proper position upon the stub shaft will be held in that position by means of a set nut 69. This will give a certain amount of rotary adjustment, and movement toward and from the working pass may be effected by this means. The lever 68 is for the purpose ofgiving adjustment of the stock relative'to the plane .of the face 33. The lever is shown as pivoted at 70, and has an inturned end or toe 71 which is provided with a conical opening 72 which Wlll be engaged by a conical end 73 of a screw 74:. There is a set nut 7 5 to lock the conical end 73 in its position after it has served to move the lever upon its pivot 70.

It is well known that in rolling mills a.

pair of rolls which form the stock will pass the stock forward with considerable force, the bite at the working pass of such forming rolls being very strong. In the present instance this naturally strong forwarding action from between a pair of forming rolls is taken advantage of for passing the formed material directly, and Without engagement with any other surfaces than those which have engaged it'for its formation, into a coiling device and utilizing such strong forwarding movement for forcing the stock through the coiling device. In the present illustration a solid coiling die is employed. The die is illustrated in lon itudinal section in Fig. 14 and bears the re erence character 76, it being a solid die and having at one end 77 a configuration to give the proper conformational outlines to the coil 78 which it is to produce. Oneside of the die is open, see Fig. 1, for receiving the stock as this passes from between the engaging faces 40 and 33. By reference to Fig. 6 it will be seen that the coiling die is located a short distance from the working pass of these rolls, and it will also be seen that the stock is not engaged by any surface after passing from between such working pass until it enters the die.

The die in the present instance is shown as having a cylindrical exterior which is seated in a socket in a supporting member 7 9 and will be clamped in its proper longitudinal and rotary position of adjustment by means of a set screw 80. The supporting member 7 9 is provided with a longitudinally. disposed bolt slot 81 for receiving a bolt 82 which enters an extension 83 of the machine frame. .This bolt and slot will permit the member 7 9 to be adjusted longitudinally for bringing the ceiling die nearer to or farther from the workin face 33 of the roll 32. The die may be given its proper inclination, that is as respects the longitudinal axis, by a pair of adjusting screws 8 l-85 which have screw threaded connectionwith the member 79 and abut at their ends against the machine frame and will move the member 79 upon the pivot afforded by the head and washer 86 of the bolt 82. For the purpose of rigidly supporting the member 79 in its position of adjustment aplate 87 is mounted upon the extension 83 and will, by means of set screws 88, clamp the member 79 against a suitably formed ledge upon the extension 83.

The operation of the machine is substantially as follows: Thestock guide 62 will be given its proper angular adjustment upon its shaft 67 for bringing the stock 42 which is fed over the surfaces 63 and between the guides 6464 into the plane of the die face 33 of the external roll 32. The stop face 53 will be adjusted for limiting the pressure between the rolls 3738 and the roll 32, and the set nuts 51 will be adjusted for holding 'the rolls 3738 to their work and stop member 53 against its seat. The coiling die 76 will be adjusted in its carrying member 79 longitudinally for bringing it to the roper position relative to the plane of the ace 33 and will be adjusted angularly for bringing its open side to the proper position for engaging the material as this comes from between the rolls 38-32 at their working pass. The member 79 will be adjusted longitudinally and rotarily also for bringing the die into its proper position, and the various set nuts will be clamped in position. The gearing will, by means of the driving pulley, ro tate the die faces 33 and 39 and 40, at the same surface speed in the same direction which will draw the strip of stock between the rolls 37 and 32 and give it its general configuration. The pressure between the rolls 37 and 32 may be stronger than that between the rolls 38 and 32, which latter rolls by their engagement give the finishing conformation to the stock and pass this on into the coiling die and coil it around the insu-' lated wire 42 which passes through the die opening. The die face 33 engages that side of the stock which will be on the outside of the coil, and the roll faces 36 and 40 engage the side of the stock which will be on the inner side of the coil. 1
